METAL-PLANINC MACHINE.

SPECIFICATION forming part ofY Letters Patent No. 531,489, dated December 25, 1894.

Application filed May 28, 1890. Serial No. 353,470. (No model.)

To all whom it may concern:

Be it known that I, JOSHUA S. WHEELER, a citizen of the United States, and a resident of Worcester, in the county of Worcester and State of Massachusetts, have invented certainnew and useful Improvements in Metal-Planing Machines, of which the yfollowing is a specification, accompanied by drawings which form a part of the same, and in which- Figure 1 represents a metal planing machine in side elevation, embodying 4my invention. Fig. 2 represents a top View of one of the posts. Fig. 3 is a sectional viewof the same on linek X, X, Fig. l. Fig. 4 is a lsectional view on line Y, Y, Fig. 1. Fig. 5 is a top view of a portion of the table. Fig. 6 is a bottom view of a portion of the table. Fig. 7 is a transverse sectional view of the table on line Xa, X, Fig. 6. Fig. 8 is a transverse sectional vview, on line X', X', Fig. 6. Fig. 9 is a transverse sectional View on line X2, X2, Fig. 6. Fig. 10 is a transverse sectional view on line X3, X2, Fig. 6. Fig. 1l is a sectional view of the bed on line X4, X4, Fig. 12, and Fig. 12 represents a portion of the bed of the machine, a portionA of the same having been broken away in order to disclose one of the'oil pockets.

Similar letters refer to similar parts in the several views.

My invention relates to certain improvements in the construction ofthe frame work of the machine, in the construction of the table and in certain impro'vements whereby the better lubrication of the table is secured.

Referring to the accompanying drawings, A denotesrthe bed of the machine, A the reciprocating table, and B one of the upright posts, attached to the sides of the bed.

The post B is cast ina single piece provided at its lower endV with the anged end B by which it is attached to the side of the bed A. The upright portion of the post is provided with the Iiange B2, which forms the way upon which the vertical adjustment of the cutting tool is effected in the usual manner. The post is also provided with the oblique hanged ribs B2, B4 and B5, one end`of each of the oblique flanged brace ribs, being integrally consurface of the table to receive chips, dirt, &c.,

incident.- to the\operation of planing.

At the end of the table are the'lugs d, d, d, d, provided with holes e,to receive pins,\which are held in the lugs d outside of the surface of the table, allowing work of greater length to be held upon the table by means of the resisting pins held outside and beyond the surface of the table itself. p

The table consists of a shell, cast in a single piece, andl having openings Ba, B, upon its lower side and provided with a series of cylindrical bosses f, f, integral with the shel1to receive the holes b, b, which extend entirely through the bosses f, f, thereby aording a longer support for the pins held in the holes b, and allowing chips, dirt, &c., to fall through and prevent the clogging of the holes.

The shell of which the table consists extends across the top, at g, forming the upper surface upon which theWorkissupported,andatinter-v vals it is thickened to receive the T shaped slots a. The shell also extends down the sides of the table at h and uponrthe lower side of the table toward the center at j, forming the V shaped bearingsj.

Through the center of the table and lengthwise thereof is a row of bosses lo, lo, Figs. 6, 8, 9 and lO, and integral with the central row of bosses lo is the plate Z, which forms a bed upon which the rack is bolted, by a series of bolts shaped bearings j', are lled with oil, when the machine is in use, and the oil is fed to the bearing surfaces by means of the fibrous wicks fn., fn, Fig. l0. A Y

The bed a portion of which is shown in Figs.

IOO

11 and 12, consists of a shell, cast in a single piece, and composed of an inner wall p and an outer Wall p', open at lthe bottom at p2, and forming a shell rectangular in form, the outer and inner walls being united at their upper edges by the walls of the V shaped ways fr, a", along which the table is moved in the operation of planing.

At intervals along the bed and immediately beneath the V shaped Ways fr, fr, are pockets s, inclosed in Walls s', s', cast integrally with the bed itself. Holes are formed in the Walls of the V shaped Ways r, r, as shown at t, t, Fig-.11, communicating with the pockets s, and oil held in the pockets s, is fed to the ways by the fibrous wicks u, u. The openings t, t, are placed near the upper edges of the V shaped web, which unites the inner and outer Walls of the bed, allowing the lubricating material, to dow down the "V shaped Ways by its own gravity.

What I claim as my invention, and desire to secure by Letters Patent, is

The combination in the table of a planing machine, of a shell open upon the under side and having an upper surface g, upon which the work is supported and vertical sides h, a central longitudinal rib l and a series of transverse ribs m, all cast integrally in one piece and a series of bosses integral with said shell and also with said central and transverse ribs, said bosses being provided with holes to receive the work holding pins, substantially as described.

Dated at Worcester, in the county of Worcester and State of Massachusetts, this 15th day of May, 1890.
